Police said that officers first noticed Crowl parked outside the department's east precinct in April.

Authorities said that Crowl had been seen filming police officers and seemed to be watching officers enter and leave the building during shift changes.

Investigators said on Sunday afternoon, a police sergeant saw Crowl parked across the street from the precinct. The sergeant requested by police radio that officers contact Crowl. As soon as the radio transmission was broadcast, Crowl drove away, authorities said.

Police said when Crowl returned to the police station at 9:30 p.m., officers were able to get him out of his vehicle.
